A: A group of tissues that work together to perform a specific function is called an organ. The human body has many organs, and each has its own specific function. In some cases, groups of organs also work together to serve a larger function, and this is known as an organ system.
For example, the heart pumps blood, the liver (which has more than 500 functions) helps get rid of bodily poisons and stores vitamins, and the brain interprets electrical signals and makes decisions about what to do. Different organs functioning together are termed systems (or sometimes, organ systems). For example, the respiratory system consists of the nose, pharynx, larynx, trachea, bronchi, and lungs.
